1、定义一个GPS管理类：
GPSLocationManager.h:
#import#import "SingletonTemplate.h"// GPS定位#import #import @interface GPSLocationManager : NSObject singleton_for_header(GPSLocationManager)#pragma mark - GPS定位成功与失败的回调block/** * GPS 定位成功与失败的block */@property (nonatomic, copy) void (^gpsSuccessBlock)(CLLocationDistance longitude, CLLocationDistance latitude);@property (nonatomic, copy) void (^gpsFailureBlock)();- (void)addGpsSuccessCallback:(void (^)(CLLocationDistance longitude, CLLocationDistance latitude))callback;- (void)addGpsFailureCallback:(void (^)())callback;#pragma mark - 开启/停止 GPS定位/** * 开启GPS定位 * 停止GPS定位 */- (void)startGPSLocation;- (void)stopGPSLocation;#pragma mark - 通过经纬度坐标获取当前地理位置/** * 通过经纬度坐标获取当前地理位置 * * @param longitude 经度 * @param latitude 纬度 */- (void)gpsLocationInfoByLong:(CLLocationDistance)longitude lat:(CLLocationDistance)latitude locationInfo:(void (^)(CLPlacemark *gpsInfo))info;@end
GPSLocationManager.m文件内容：
#import "GPSLocationManager.h"#import "MHLocationConverter.h"@interface GPSLocationManager ()@property (strong, nonatomic) CLLocationManager *locationManager; // 定位管理器@property (assign, nonatomic) CLLocationDistance longitude; // 经度@property (assign, nonatomic) CLLocationDistance latitude; // 纬度@property (strong, nonatomic) CLGeocoder *geocoder; // 位置反编译@end@implementation GPSLocationManagersingleton_for_class(GPSLocationManager)#pragma mark - 开启GPS定位- (void)startGPSLocation{ // 检查是否开启了定位服务 if (![CLLocationManager locationServicesEnabled]) { // 定位不可用 DEF_DEBUG(@"定位服务没有开启"); return; } self.locationManager = [[CLLocationManager alloc] init]; // 判斷是否 iOS 8 if ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) { // [self.locationManager requestAlwaysAuthorization]; // 永久授权 [self.locationManager requestWhenInUseAuthorization]; //使用中授权 } self.locationManager.delegate = self; // 所需的位置精度 self.locationManager.desiredAccuracy = kCLLocationAccuracyBest; // 指定用米的最小距离更新 self.locationManager.distanceFilter = kCLDistanceFilterNone; // 开始定位 [self.locationManager startUpdatingLocation];}- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{ DEF_DEBUG(@"设备旋转指向:%u",status);}- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{ DEF_DEBUG(@"定位失败:%@",error); // GPS 定位失败 if (self.gpsFailureBlock) { self.gpsFailureBlock(); }}- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{ // WGS-84坐标转为BD-09坐标 CLLocationCoordinate2D coord = [MHLocationConverter wgs84ToBd09:newLocation.coordinate]; DEF_DEBUG(@"GPS 定位转换为百度地图用的经度:%f, 纬度:%f", coord.longitude, coord.latitude); // 得到转换后的经纬度 self.longitude = coord.longitude; self.latitude = coord.latitude; // GPS 定位成功 if (self.gpsSuccessBlock) { self.gpsSuccessBlock(self.longitude, self.latitude); }}#pragma mark - 停止定位- (void)stopGPSLocation{ [self.locationManager stopUpdatingLocation];}#pragma mark - 通过经纬度坐标获取当前地理位置- (void)gpsLocationInfoByLong:(CLLocationDistance)longitude lat:(CLLocationDistance)latitude locationInfo:(void (^)(CLPlacemark *gpsInfo))info{ /** * 反编译经纬度 */ // 传入的坐标系是BD-09的 CLLocationCoordinate2D coord; coord.longitude = longitude; coord.latitude = latitude; // 从BD-09坐标转回到GCJ-02，再进行位置转化 CLLocationCoordinate2D newCoord = [MHLocationConverter bd09ToGcj02:coord]; // 防止循环引用 __unsafe_unretained typeof(self) _self = self; _self.geocoder = [[CLGeocoder alloc] init]; [_self.geocoder reverseGeocodeLocation:[[CLLocation alloc] initWithLatitude:newCoord.latitude longitude:newCoord.longitude] completionHandler:^(NSArray *placemarks, NSError *error) { // 当前位置的数据信息 if (error == nil && placemarks.count > 0) { CLPlacemark *placemark = [placemarks objectAtIndex:0]; DEF_DEBUG(@"定位结果: %@", placemark); // block回调 if (info) { info(placemark); } } else if (error == nil && placemarks.count == 0) { DEF_DEBUG(@"经纬度逆编译没有结果返回"); } else if (error != nil) { DEF_DEBUG(@"经纬度逆编译错误: %@", error); } }];}#pragma mark - block- (void)addGpsSuccessCallback:(void (^)(CLLocationDistance longitude, CLLocationDistance latitude))callback{ self.gpsSuccessBlock = callback;}- (void)addGpsFailureCallback:(void (^)())callback{ self.gpsFailureBlock = callback;}@end 2、在AppDelegate里面实现 gpsLocate方法，开启定位
#pragma mark - GPS定位- (void)gpsLocate{ // 防止循环引用 __unsafe_unretained typeof([GPSLocationManager sharedGPSLocationManager]) gps = [GPSLocationManager sharedGPSLocationManager]; // 开启定位 [gps startGPSLocation]; // 定位结果 gps.gpsFailureBlock = ^(){ // 定位失败 }; gps.gpsSuccessBlock = ^(CLLocationDistance longitude, CLLocationDistance latitude){ // 停止定位 [gps stopGPSLocation]; // 定位成功 NSLog(@"定位成功，经度:%f, 纬度:%f", longitude, latitude); // 逆编译地区 [gps gpsLocationInfoByLong:longitude lat:latitude locationInfo:^(CLPlacemark *gpsInfo) { // NSLog(@"写法一，当前地理位置信息: %@", gpsInfo); // 获取城市 NSString *city = gpsInfo.locality; if (!city) { // 四大直辖市的城市信息无法通过locality获得，只能通过获取省份的方法来获得（如果city为空，则可知为直辖市） city = gpsInfo.administrativeArea; } NSLog(@"city = %@", city); NSMutableString *mutable = [[NSMutableString alloc] initWithString:city]; if ([mutable rangeOfString:@"市辖区"].location != NSNotFound) { [mutable deleteCharactersInRange:NSMakeRange([mutable length]-3, 3)]; city = mutable; } }]; };}
